Abstract

The anion-induced outer surface interaction of Q[n]s is an important driving force in the construction of Q[n]-based supramolecular frameworks. In this work, a symmetric tetramethyl-substituted cucurbit[6]uril (TMeQ[6]) is selected as the basic structural block. Using the anion-induced outer surface interaction of Q[n]s derived from [Cd_xCl_y]^n- anions formed by Cd²⁺ cations in a HCl medium, four different TMeQ[6]-[Cd_xCl_y]^n--based supramolecular frameworks are constructed. Three of the most common TMeQ[6]-[Cd_xCl_y]^n--based supramolecular frameworks are selected for further vulcanization, and three different CdS/TMeQ[6]-based framework catalysts with different structures and properties are obtained. The catalytic activities of these three CdS/TMeQ[6]-based framework catalysts are investigated by the coupling photocatalytic reaction of aminobenzyl, and the results showed that the catalytic activities of the three catalysts are all higher than that of pure CdS. Therefore, this work establishes that it is possible to establish a method for synthesizing the Q[n]-based framework-supported catalysts by first synthesizing TMeQ[6]-[Cd_xCl_y]^n--based supramolecular frameworks and then forming Q[n]-based framework supported catalysts by sulfurization or reduction.
